Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention displays product data on a display section at predetermined intervals while the device is on standby, and is used in electronic registers with a display function, etc. .

[Conventional technology]

Generally, for example, in an electronic register equipped with a PLU (Price Lookup) key, each
The character code of the product and the unit price data of the product are stored in the memory in correspondence with the PLU key. Then, by operating the PLU key at the time of registration, the corresponding character code and unit price data are read out from the memory and predetermined registration processing is performed, and the display section displays data corresponding to a series of registration operations, In addition, the display section of an electronic register that is not processing sales data and is on standby may display the previous display in cascade, or may have been switched to display the time, or as shown in Japanese Patent Application Laid-Open No. 56-35261. It is known that the date is displayed on the display only at the beginning of the day.

[Problem that the invention seeks to solve]

However, conventionally, the character code and unit price data of the product stored in the memory are simply used at the time of registration, and when the product is in a standby state where sales data is not being processed, the rich information in the memory is used. There was a lot of waste as the display area was not being used effectively.

An object of the present invention is to read out and display a plurality of product data consisting of product characters and product prices from a storage means at predetermined time intervals during a standby state in which sales data processing is not being performed, and display the stored product data. and to enable effective use of the display section.

[Means for solving problems]

The means of this invention are as follows.

Judgment means 1 (see the functional block diagram in Figure 4)
The same applies hereafter) determines that sales data is not being processed, that is, no key input has been made to the electronic register (for example, CPU 1, etc.)
_S2 ).

When the determining means 1 determines that sales data processing is not being performed, the time measuring means 2 measures a predetermined period of time, such as 10 seconds (timer 6 or the like).

Each time the timer 2 measures the predetermined time, the readout means 3 reads the information stored in advance, for example, from the
At least one product data is sequentially read out of a plurality of product data such as 120 yen, carrot 93 yen, etc. (CPU 1, etc., S ₈ ).

In addition, in parentheses, numbers or step numbers in the embodiments are added for reference in order to clarify how each of the above-mentioned means is embodied in the embodiments.

[Effect]

The operation of the means of this invention is as follows.

In an electronic register with a display function that stores a plurality of product data including product characters and their prices and displays this product data on a display unit as sales data is processed, the determination means 1 determines that the sales data is not processed. When the determination is made, the reading means 3 reads out at least one product data from among the plurality of product data and displays it on the display section every time the clock means 2 measures a predetermined time.

Therefore, the time when the display section is not used for sales data processing can be utilized, and the product data stored for sales data processing can be effectively utilized for advertising products to customers.

〔Example〕

Hereinafter, one embodiment will be described with reference to FIGS. 1 to 3.

FIG. 1 shows a schematic system configuration diagram of an electronic register, and reference numeral 1 indicates a CPU. W signal,
A chip designation signal is output, and a control signal output from the print control section 4 is input. Further, the CPU 1 communicates with each of the control units 2, 3,
4 and the PLU memory 5. Further, the CPU 1 inputs data from the input buffer IN via the data bus DB, and outputs the data to the display buffer DI provided in the display control section 3 and the print buffer PR provided in the print control section 4, respectively. Furthermore, data is exchanged with the PLU memory 5. Further, the CPU 1 outputs a count-up signal UP and a signal CL for erasing the count contents of the timer 6 to the timer 6, respectively. This timer 6 counts the input signal UP,
This count data is output to the decoder 7. The decoder 7 outputs a "1" signal to the three-state buffers 8 ₁ and 8 ₂ when the input counting data reaches a value indicating the time when 10 seconds or more or 3 minutes or more have passed. This three-state buffer 8 ₁ ,
A gate signal is input from the CPU 1 to ₈₂ , and when this gate signal is input, the "1" signal is output to the data bus DB.

The input control section 2 inputs a timing signal to the input section 9.
KP is output, and when a key operation is performed in the input section 9, a timing signal KP is selected according to the operated key and inputted to the input buffer IN as a key input signal KI. The input section 9 includes a number key,
It is equipped with a clear key, PLU key, cash/deposit key, etc., as well as a mode switch for specifying each mode such as ``registration'' and ``setting.'' Further, the display control section 3 outputs the digit signal DG and the segment signal SG obtained by decoding the data of the display buffer DI to the display section 10 to display amount data and the like. The print control unit 4 also prints a print drive signal HD generated when the print position signal TP of a print drum (not shown) provided in the print unit 11 matches the data in the print buffer PR. Send to Department 11. Then, the printing unit 11 receives a print drive signal.
Prints amount data etc. on recording paper according to HD.

Further, each storage area of the PLU memory 5 stores a series of data consisting of a character indicating a product name and unit price data of the product, and whether or not this series of data is displayed when electronic register registration is interrupted. A display flag is stored that specifies whether the The row address of each storage area is associated with the PLU number input by operating the numeric keys.

Next, the operation of this invention will be explained. First, set the mode switch on the input section 9 to "setting" mode, operate the numeric keys and the PLU key in sequence,
Next, operate the numeric key □1 or □0 to set the display flag in the corresponding storage area of the PLU memory 5. When the mode switch is set to the "registration" mode, the operation according to the flow shown in FIG. 2 is always executed.

That is, in executing step _S1 , the contents of the input buffer IN are transferred to the A register of the CPU1. Next, the program moves to step _S2 , where it is determined whether the contents of the A register are "0" or not.If it is determined not to be "0" and there is data input, the program moves to step _S3 . In executing step _S3 ,
A signal CL is output from the CPU 1 to the timer 6, and its contents are cleared. Next, the process moves to step _S4 , where a processing operation according to the key code in the A register is executed, and then the process returns to step _S1 . If the content of the A register is "0" in step _S2 , it is determined that no key operation has been performed, and the process moves to step _S5 . In executing step _S5 ,
The signal UP is output from CPU1, and the count value of the timer is counted up. Next, the process moves to step _S6 , in which the gate signal is output from the CPU 1 to the three-state buffer ₈₂ , from which it is determined whether or not a "1" signal is output. It is assumed that the time limit has not been reached and the process returns to step _S1 .

When it is determined in step _S6 that three minutes have elapsed on the timer 6, the process moves to step _S7 . step
In the execution of _S7 , the initial value of the PLU address specifying each storage area of the PLU memory 5 is set in the X register. Next, proceed to step _S8 ,
The contents of the storage area M(X) of the PLU memory 5 addressed by the X register are read into the A register. Next, proceed to step _S9 ,
A determination is made as to whether or not the display flag "11" is included in the A register, and if it is determined that the display flag is present, the process moves to step _S10 . In step _S10 , the signal CL is output from the CPU 1 and the contents of the timer 6 are cleared.
Next, the process moves to step _S11 , where a series of data consisting of the character code and unit price data in the A register is transferred to the display buffer DI and displayed on the display section 10, and then the process moves to step _S12 . Even if the display flag is not stored in the A register in step _S9 , the process moves to step _S12 and the address in the X register is updated. Next, the process moves to step _S13 , where it is determined whether the content of the X register is greater than the final address of each storage area of the PLU memory 5 and has reached the address END.If it is determined to be YES, the process proceeds to step _S7 . return,
If it is determined no, the process moves to step _S14 . step
When executing _S14 , the contents of the input buffer IN are A.
Transferred to register. Next, the process moves to step _S15 , and if it is determined that the contents of the A register are not "0", it is assumed that a key operation has been performed, and the process returns to step _S3 ; if it is determined that the content is "0", the process returns to step S3. Move to ₁₆ . In executing step _S16 , the CPU
A signal UP is output from 1, and the contents of timer 6 are incremented by 1. Next, the process moves to step _S17 , where a gate signal is output from the CPU 1 to the three-state buffer ₈₁ , and it is determined whether or not a "1" signal is output from there, that is, after the timer 6 is cleared in step _S6. It is determined whether 10 seconds have elapsed, and if not, the process returns to step _S14 .
Continue to display the PLU character and unit price. Ten
When the second has elapsed, the process returns to step _S8 and the next PLU data is displayed.

For example, as shown in Figure 3, the number key □1,
When the PLU keys are operated in sequence, the contents of the storage area of the PLU memory 5 corresponding to the input numerical data "1" are read out, and the character "Cabetsu" and unit price "120" of the product are displayed on the display section 10. Ru. Next, operate the numeric key □2 and the PLU key,
The same operation as described above is performed and "Carrot 93" is displayed on the display section 10, and when the cash/deposit key is further operated, "Gokei 213" is displayed on the display section 10.
will be displayed and a receipt will be issued at the same time.

Assuming that 3 minutes have passed without any key operation after the customer's registration is completed, steps _S6 to S6 are performed.
As a result of sequential execution of _S17 , a series of data stored in the first storage area of the PLU memory 5 is read out, and "cabbage 120" is displayed on the display unit 10. Thereafter, the timer 6 counts up and when it is determined in step _S17 that 10 seconds have passed since the data was displayed, the contents of the second storage area of the PLU memory 5 are read out, but the display flag is Since it is “0”, the data “onion 48” in the next third storage area is displayed on the display unit 10. In exactly the same way, a series of data in each storage area of the PLU memory 5 is sequentially read out every 10 seconds, and among these data, the data in which the display flag is stored is sequentially displayed on the display unit 10 every 10 seconds. When the reading of the contents of each storage area of the PLU memory 5 is completed, steps S ₁₃ and S ₇ are executed, and as a result, the PLU memory 5 starts reading from the first storage area again, and the display unit 10 The same display as above is repeated every 10 seconds. By the way, if you perform a registration operation for the next customer while the contents of the PLU memory 5 are being switched and displayed every 10 seconds, this key operation will be detected in step _S15 and the process will proceed to steps _S3 and S. _Four
are executed sequentially, the timer 6 is cleared, and the input processing is executed. Then, when three minutes have passed after the registration for the customer is completed, the display section 10 displays
The series of data in the PLU memory 5 is displayed repeatedly in sequence every 10 seconds.

As mentioned above, in this embodiment, when 3 minutes have passed after the registration for the customer is completed, the display unit 10
Since the series of data designated for display in the PLU memory 5 is automatically displayed in sequence, there is no need for the operator to perform any particular display switching operation, which is convenient. In addition, the above embodiment has the advantage that out of the series of data stored in the PLU memory 5, a series of data to be displayed every 10 seconds can be freely designated for display.

Note that in the above embodiment, the PLU memory 5
Although each series of data is associated with a numerical value input in conjunction with a PLU key, the present invention is not limited to this, and each series of data may be associated with a department key.

Further, in the above embodiment, a series of data instructed to be displayed in the PLU memory 5 is switched and displayed on the display section 10, but the present invention is not limited to this, and the display data is moved one digit at a time in one direction. It may also be configured to display the text as so-called flowing text.

Furthermore, in the embodiment described above, a series of data is automatically switched and displayed in sequence when three minutes have elapsed since the registration operation was interrupted, but the present invention is not limited to this. may be provided.

Further, in the embodiment described above, the series of data is switched and displayed, but the present invention is not limited to this, and it is also possible to sequentially pronounce the series of data by voice.
